I'm currently working on compiler details with Chris. He sent me some
patches to produce cleaner code for ROM calls (register allocation
issues), and after we have consolidated these, there'll be both patches
and binary releases for Linux and Windows available.
This will probably be based on egcs-1.1.1 to circumvent the library
problems present in gcc and egcs-1.1.
